CATTLE GUARD.

Application filed December 27, 1923. Serial No. 683,007.

To all 107mm it may conga m:

Be it. known that I, .losrrn GIBsoN, a citizen of the Dominion ofCanada, residing at Diamond City, in the county of Lethbridge andProvince of Alberta, Canada, have invented certain new and usefulImprovements in Cattle Guards, of which the following is aspecification.

My present invention relates to improvements in cattle guards and hasfor its principal object the provision of a simple, cheap and easilyconstructed cattle guard for use in connection with railroads and thelike, for preventing the passage of cattle where such is necessary ordesired.

A further object is the provision of such a device which will notinterfere with the passage of trains or the like but will foil theattempts of an animal to cross without seriously punishing or doinginjury to the animal.

To the accomplishment of these and related objects, my invention residesin the construction, combination and arrangement of the variouscooperating elements as shall be hereinafter more fully described,illustrated in the accompanying drawings and pointed out in the claimshereunto appended.

In the drawings, forming a part of this specification, wherein likecharacters of reference designate like parts throughout the severalviews,

Figure 1 is a plan of a portion of conventional railroad trackillustrating the application and preferred embodiment of my invention,

Figure 2 is a transverse section taken on the line 2-2 of Figure 1, and

Figure 3 is a longitudinal section of one of the rollers illustrating apossible form of mounting.

Positioned between and transversely of the track designated by thenumeral 6, I provide a pair of spaced supports 4 having inturned ends 5disposed at right angles to the body portion, said angle ends beingadapted for connection to the rails. Suitable bolts or rivets 7 are usedfor effecting such connection and washers or other spacers notillustrated my be employed if found necessary in practice.

A corresponding and regular longitudinal series of perforations 8, inthese transverse supports 4 are adapted to receive the spindles 9 ofsquare or other suitably shaped bars 10 laid parallel with the track 6,These bars will be of any suit-able length and are carried by thespaced, transversely-disposed supporters 4 adapted to receivetheirspindled ends. In Figure 3 I have illustrated a possibleconstruction for the spindle bearing ends of the rollers wherein thepintle-like axle 9 extends but a short distance exterior to the roller10 and is inserted deeply therein. A suitable sleeve or collar 11 whichmay be provided with an inturned annular flange, not shown, is receivedby the end of the roller to substantially strengthen the same. Washersmay be carried by the spindles between the ends of the rollers and thetransverse support.

To relieve any undue strain such as would result from unnecessary Spaceallowed between the ends of the rollers 10 and the transverse support 4my invention provides for a subsequent adjustment of the distancebetween such transverse supports 4. This may be in the form of elongatedperforations in the inturned ends 5 adapted for the reception of thesecuring means 7.

It will be obvious that while it may not be found advisable to providemeans for adj ustably spacing the parallel rollers 10 which willpreferably be square in cross section, they may be spaced either toallow of or refuse the reception of an animals hoof, as found best inpractice.

While I have but described the construction and mounting of my devicefor positioning between the tracks, it will be ap parent that the samedesign and arrangement will be equally applicable to location exteriorto the tracks with the pro-vision of suitable means for mounting theremote ends of the transverse supports 4:. It will further be obviousthat those sets of rollers which may be of any desired length can alsobe provided in any suitable number of sets placed successively one afteranother.

As many changes could be made in the above description and manyapparently widely differentembodiments of my invention constructedwithin the scope of the appended claims without departing from thespirit or scope thereof, it is intended that all matters contained inthe accompanying specification and drawings shall be inter preted asillustrative and not in a limited sense.

What I claim as new and desire to secure by Letters Patent is l- Th c mnat on with railr ad t a ks or the like, of a device of the characterdescribed comprising a pair of spaced sup porting members disposedtransverse y of the tracks, having perforated. offset ends disposed atright angles to the body portion and lying parallel with said rails;securing means adapted to pass through the perforations in said ends andregistering apertures in said rails; said supporting members each havinga regular and corresponding, longitudinal series of perforations; aplurality of rollers disposed parallel to said tracks; spin dles mountedin the ends thereof adapted to be rotatably carried by the perforationsin said transverse supports and sleeves received by the ends of saidrollers.

2. The combination with railroad tracks or the like, of a device of thecharacter described comprising a pair of spaced supporting membersdisposed transversely of the tracks, having otlset ends disposed at;right angles to the body portion and lying. parallel with said rails;elongated perfo-l rations located in said oi'l'set ends; securing meansadapted to pass through such perforations and registering apertures insaid rails; said supporting members each having a regular andcorrespondin longitudinal series of perforations; a plurality o'l'rollers disposed parallel to saidrtracks; spindles mounted in the endsthereof adapted to be rotatablv carried by the perforations in saidtransverse supporting members and sleeves received by the ends of saidrollers.
